PUMP-FRAME.

SPECIFICATION forming part of Letters Patent No. 256,855, dated April25, 1882.

Application filed June 30, 1881. (No model.)

To all whom it may concern Be it known that I, JAMES PRESTON, of thecity, county, and State of New York, haveinvented a new and ImprovedPump-Frame, of 5 which the following is a specification.

The object of my invention is to provide a new and improved pump-framewhich facilitates changing the pump from a right-hand to a left-handpump, and vice versa.

10 In the accompanying drawings, Figure 1 is a front elevation of a pumpfastened to my improved pump-frame. Fig. 2 is a cross-sectionalelevation of the same, and Fig. 3 is a horizontal sectional view of thesame on line 15wm,Fig.1.

Similar letters of reference indicate corresponding parts.

The pump-frame consists of a plate, A, provided with two segmental orconcave projec- 2o tions, B B, with grooves in the outer edges toreceive two collars or annular projections, O O, of the pump-cylinder D,which is held to the plate or frame A by a semicircular or U- shapcdbaud, E,fitting over a collar, 0, of the The pump-cylinder is thus freeto turn on its longitudinal axis, so that the spout or nozzle F can beturned to project in any desired direction; but the cylinder cannot bemoved vertically or laterally. A con- 0 necting-rod, G, is pivoted atits lower end to the frame A, on the center line of the same,

and its upper end is pivoted to the pumphaudle, near the upper end ofthe same. The upper end of this pump-handle H is pivoted to thepiston-rod J, which is guided in a projec- 5 tion, K, at the upper endof the frame A.

If the pump is to be reversed-that is, if the handle is to he placed onthe other side of the cylinder D--the upper end of the connectingrod Gis detached from the handle H, and the 0 latter is turned to the otherside of the cylinder, when the rod G is again attached to it. Thefulcrum of the handle H is at the upper end of the rod G, and swings toand from the piston-rod when the handle is worked. 5

I am aware that pump-cylinders have been secured to a supporting-frameso as to turn and bring the discharge-pipe on different sides; also,that fulcrum-supports for the handle have been pivoted to the frame; but50 i.

What I claim as new and of my invention 1s The handle fulcrum-rod G,pivoted at its lower end in the axial line of a turning pumpcylinder,and pivoted detachably to the pump- 5 handle at the other end, wherebyit will be in its true relative positionvto the handle, no matter towhat extent the cylinder is turned.
